Question

A rectangular beam has a cross section of 5 cm wide by 10 cm deep and a maximum shear of 2250 N. What is the maximum shear stress in the beam? (a) 416 kPa (b) 675 kPa (c) 567 kPa (d) 790 kPa

Answer 1

maximum shear stress = 675 kPa

Step-by-step explanation:

Given data

wide section b = 5 cm

deep section d = 10 cm

shear = 2250 N

to find out

the maximum shear stress in the beam

solution

we know the maximum shear stress in the beam formula that is

maximum shear stress = 3/2 × shear / b d

maximum shear stress = 3/2 × 2250 / 50×100

maximum shear stress = 0.675 N/mm²

maximum shear stress = 675 kPa
